Have I noted enough of his traits to show that in his dominant character he had become the archtypical pioneer? Let me note them once more: an uncritical and uncalculating temper, a large, loose desire for an expansive and expensive all-round life, a habit of accepting from his surroundings "the prevailing ideas and modes of action," a naïve worship of success and prestige, an eager and inveterate interest in mechanical inventions and commercial speculation, an instinctive habit of subjugating all loyalties to personal and domestic loyalties. To this let us add, finally, the versatile career of the jack-of-all-trades. "I have been through the California mill," he said, "with all its 'dips, spurs and angles, variations and sinuosities.' I have worked there at all the different trades and professions known to the catalogues." And once, as if to show that he had qualified for the popular rôle and had forestalled what Mr. Croly calls the distrust and aversion of the pioneer democracy for the man with a special vocation and high standards of achievement, he drew up a list of his occupations and found that he had been a printer, a pilot, a soldier, a miner in several kinds, a reporter, a lecturer and a publisher; also "an author for twenty years and an ass for fifty-five." It is only with all this in mind that we can grasp Mark Twain's instinctive conception of the literary career. He never thought of literature as an art, as the study and occupation of a lifetime: it was merely the line of activity which he followed more consistently than any other. Primarily, he was the business man, exploiting his imagination for commercial profit, his objects being precisely those of any other business man--to provide for his family, to gain prestige, to make money because other people made money and to make more money than other people made. We remember how, in 1868, he had written to his brother Orion: "I am in for it now. I must go on chasing [phantoms] until I marry, _then_ I am done with literature and all other bosh--that is, literature wherewith to please the general public. I shall write to please myself then." Similarly, in 1899, almost at the other end of the span of his active life, he wrote to Mr. Howells: "For several years I have been intending to stop writing for print as soon as I could afford it. At last I can afford it, and have put the pot-boiler pen away." Those two utterances show us clearly that the artist in him was sufficiently awake at the beginning and at the end of his career to realize, in the one case, that he was not living the creative life, and in the other that he had not lived it--for certainly his marriage had not relieved him from the necessity of pleasing the general public! Between whiles, the creative instinct of the artist had been so supplanted by the acquisitive instinct of the pioneer that he had no conscious sense of control over his life at all: he was not the artist,
